Question

我想创建一个快速的图片/电影查看器 - 用于庆祝生日。首先，我想展示一些图片 - 然后是电影 - 再展示一些图片。第一个图片动画显示正常，电影开始正常，并抓住AVPlayerItemDidPlayToEndTimeNotification再次启动图片，但第二个动画永远不会开始 - 我无法解决这个问题？ - DoShow1无法正常工作 - 请在那里建议任何人？

Answer 1

    [self dismissViewControllerAnimated:YES completion:Nil];
    [self DoShow1];

这可能是连续调用，动画不会在视图被解散的同时开始。

在视图之后调用的完成处理程序中尝试它驳回

[self dismissViewControllerAnimated:YES completion:^{
        [self DoShow1];
    }];

无法获得第二个图像动画 - 最近发生了什么？
